Figure 12. Use an External Supply to Power the MAX14824
External Power
The device is powered by VCC and the 5V regulator, V5.
VL is a reference voltage input to set the logic levels of
the microcontroller interface. The logic and SPI interface
are operational when V5 and VL are present even if VCC
is not present.
Connect LDOIN to V5 to power the V5 input with an
external supply (Figure 12). This configuration disables
operation of the internal 5V regulator and reduces power
consumption.
